Problems solved by technology

[0003] 1. The original tunnel kiln changes the temperature in the kiln by changing the speed of air and gas. The sintering temperature has a large range of changes, and the range of gas flow rate changes cannot be accurately controlled, which affects the sintering quality of refractory materials.
[0004] 2. In the combustion process of the original tunnel kiln, gas and air are not easy to turbulence, that is, it is not easy to fully mix, the combustion is not sufficient, and a large amount of polluting gas is generated during the process, and the amount of polluting gas generated is not easy to control
[0005] 3. The original tunnel kiln has a low degree of intelligence, and cannot adjust the speed ratio of air and gas according to the temperature change in the kiln in real time, and the adjustment of the burner angle, etc.
[0006] Fourth, the original tunnel kiln has a large temperature difference between the upper and lower sides of the kiln when sintering refractory materials, and the effect of taking various measures to reduce the temperature difference in the kiln is not obvious

Abstract

The invention discloses a temperature self-adjusting device for inner tunnel kilns. The device comprises a kiln body, a temperature adjustment burner which is installed on the side wall of the kiln body, a blower which is installed at the end part of the kiln body, a temperature sensor which is installed inside the kiln body, a PID controller and a central controller, and a temperature adjustment burner angle adjusting mechanism. The device of the invention can control the angle of the temperature adjustment burner nozzle, the fuel gas injection speed, the speed of temperature adjustment burner nozzle, and the kiln tail blowing rate of the tunnel kiln; sintering researches on various refractory materials can be carried out, which increases the diversity of researches; compared with the original tunnel kilns, the accuracy of temperature adjustment is increased, the efficiency is increased, the reaction rate of execution mechanism is faster, the automatic degree is higher with less pollution, and environmental protection and energy saving performance are improved.

Description

Technical field [0001] The invention relates to a temperature self-regulating device in a tunnel kiln. Background technique [0002] The burners of the original tunnel kiln are directly installed on both sides of the tunnel kiln or on the top of the kiln. The position of the burners is fixed, that is, the angle of the burners cannot be adjusted. Both sides of the kiln walls and kiln roof are piled with refractory materials. The temperature of the original tunnel kiln can only be changed by changing the injection speed of air and gas and extensively adjusting the blast speed in the kiln. Its fatal shortcomings are: [0003] 1. The original tunnel kiln changes the temperature in the kiln by changing the air and gas speed. The sintering temperature has a large variation range, and the gas flow rate variation range cannot be accurately controlled, which affects the sintering quality of refractory materials. [0004] 2. During the combustion process of the original tunnel kiln, the gas ...
